cascade 300 used to run quiet, now it makes noises, after about a year, like it is socking air or something what do I do?

I am not sure but on the Aquaclears one cause is by the impeller getting scratches around the magnet due to debris like gravel getting in and scratching that up. My suggestion would be to check to see if the impeller on the cascade 300 is removable and if it is (which I believe it is, but the ? is can you get it out), check to see if the magnet it scratched finely. If it is then google for a replacement impeller. Now that I think about it, I think they do sell them on ebay for like $7...

I would like to know that, too. Mine has started making a noise and I don't think it last ten years.

My machine has developed the same noise. The old machine I had also had a rubbing noise at the flywheel. I have used this machine heavily for the last six months.It still runs fine. I use music to mask the noise. Its not noticable.

I had the same problem, I had to move it, it was getting AC noise from the wall outlet, make sure all your power cords are away from it. (good luck)

My inline Panasonic 30NLF1 exhaust fan is extremely low noise. I have to strain to hear it. I should have added a small light to show when it is on.Buy the highest CFM you can afford.

Not using that much there is noise only when motor runs for cooling after that stop check the thermostat it's working ?

I would suspect the noise was the fan blades hitting some part of the shroud and possibly the motor is still ok but the switch should be turned off when turning the fan with your hands to see if it is hitting somewhere. The fan itself should last many years depending on the amount of dust & and duration of operation per use. try plugging a lamp into the outlet in the fan housing to confirm that the power is getting to the fan while you are there.

Sounds like a malfunction. Mine is completely silent. I would send it back.

It was quiet for awhile but in less than one heating season the fan motor developed a problem. It's pretty loud now though still heating. I've moved it out of the bedroom. Really not happy with it.

Hello Debby, The short answer to that is no, I have had two of these PW3500s and apart from the cooling fan which is very quite they make no noise, even on full load. John.

The noise I experienced sounded like the unit was under water. It was so annoying I didn't want the thing on. I finally figured out that they build all these units now to not drain water in between the compressor fan and condenser coil in the back of the unit. The compressor fan than using a sling blade to slosh the water up on the condenser coil cooling it. Although this makes it slightly more efficient, I couldn't stand the noise. One carefully placed drilled hole in the back right in front of the condenser coil and the noise is now gone. The unit is finally super quiet again (as far as window air conditioners go.

Ha, yeah that sounds right. It was difficult to fix, but what I did was drill two holes in the bottom of the unit towards the back to let the water drain out. It's the fan hitting the standing water that is making all the noise. It's difficult because unless you have access to the unit from outside the house (which I don't), you need to pull the unit out of the window, turn it upside down, and then I drilled 2 holes on the lowest parts the furthest towards the back of the unit. After that... no more noise. Also didn't seem to effect the unit either, still blows cold air. Hope that helped :) - Andy

The two I have are very quiet. Get a plumber, maybe you have a air vacuum issue.

Mine is a low hum, maybe you need more water in it or the motor could be faulty.

Mine started with a high pitched buzzing noise and now after 4 months the motor is not running right and mist output is low. I am having it replaced as I like the features. If I get one that works and does not make the noise, I will be very happy! :)

There is always going to be some noise from a thermoelectric cooler, but I recently had a few days of loud noise from the fan. Opened up the back and could not find anything loose. Eventually the fan noise went away in over the span of a week or two. Will be monitoring.

Hey, just a heads up, there is an issue with noise with the stock pump, over the fans. It may sound a little similar to fan rattling when the pump is running at full speed. To find out, attach the pump power wire to the PWM cpu cooler supply on your motherboard. If the noise goes away, its your pump.http://forum.corsair.com/v3/showthread.php?t=107252I also recommend high static pressure fans. The pair I got for mine are: Bitfenix Spectre Pros http://www.amazon.com/BitFenix-Spectre-Pro-140mm-BFF-SPRO-14025KK-RP/dp/B007OWPBP6 They can get a little loud however, but under a fan controller, should do fine.
